Mercedes Aanounces Performance Plug-in Hybrid SUV


"The GLE550e has the first plug-in hybrid powertrain ever offered in a Mercedes-Benz SUV. Its 3.0-liter V6 gasoline engine and electric motor together produce 436 horsepower. Using only electric power, Mercedes says the GLE550e can travel up to 18.6 miles and reach a speed of 81 mph."

Wow. In other words, plug it in for the commute or grocery shopping and never waste time at the gas station unless you need to go far.
Mercedes is doing exactly what I thought Lexus would do in the mid-sized hybrid crossover space two years ago. With their new XC90, Volvo and Merc are beginning to lead.  

I wonder if this the Tesla e-motor hardware they've been discussing? Or something else entirely?
